A "normal life" isn't anything you should anticipate having, with a Borderline.
Ya can't treat or relate to a Borderline as though they're a normal adult, because they're not. Unless you're willing to take extreme actions against 'em when they try to dick around with you, you'll NEVER come out ahead or get the resolution you need.
This holds true when you're being confronted with an "accidental pregnancy" or when they demand more child support, or make domestic abuse allegations, etc. It's all a challenging, enlivening GAME to them.
Borderlines are control freaks and attention whores. They'll nag and press you endlessly for things they don't even want, merely to keep tension and strife alive in your relationship, because it feels stimulating and activating for 'em.
Years ago, a Narcissist/BPD gal pal had an affair with a married man. She never relented putting pressure on him, until he left his wife and kids. A bit later in their dance, she pressed him to marry her, and (like a schmuck) he DID. Even later, she nagged him to give her a baby.
My former friend NEVER wanted to have a child or be a mother~ but because her lover said "No" to it (already having had a couple of kids with his ex-wife), she wouldn't let this issue rest. She brought this topic up CONSTANTLY, and it became an ever-present bone of contention in their relationship.
I observed their never-harmonious relationship from the sidelines. A normal, emotionally whole, healthy female would never behave in these ways... but then, she wouldn't be naive enough to get involved with a married man in the FIRST PLACE.
For many Borderlines, it's not enough for them to seduce you~ they derive EXTRA gratification and self-validation if they can steal you away from someone else! These are HIGHLY manipulative beings, folks. If you actually think that giving into their whims, desires and demands will make all their nagging stop, THINK AGAIN.
It is literally IMPOSSIBLE to please or satisfy someone with BPD features. Contentment isn't a feeling that's in their wheelhouse to accommodate.
One BPD client told me years ago, that if all felt right and calm in her world, intense feelings of anxiety would kick in. She always had to keep a project or task uncompleted, 'cause having "everything in order," produced tremendous feelings of unrest within her.
These are traits the DSM-V won't ever reveal to you about BPD. Nor will they describe a litany of anomalous behaviors and inner- experiences that are downright TYPICAL of Borderlines, and are never discussed nor explained in any other reading materials, except for my articles on this topic.
A little bit of knowledge goes a long way. The more you know, the better you can protect and preserve yourself. Read all about BPD here!
